Patented Dec. 26, 1911.

Application filed August 13, 1910. Serial No. 577,019.

T 0 all whom it may concern:

Be it known that I, JOSEPH A. SIMON, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented certain new and useful Improvements in Track-Cleaners, ofwhich the following is a specification.

My invention relates to an improved track cleaner and wheel guard and itis particularly adapted to be used in connection with the wheels ofsaw-mill carriages.

The objects of the invention are to provide a device that will permit aslight lateral movement of the carriage on its axles and which willitself not move laterally but will remain in position covering the wheeland track; to provide means which will allow the guard to freely yieldvertically on an uneven track surface; and to provide in combinationtherewith means to clear the track of sawdust or other refuse which mayenter the guard and to so construct the guard as to relieve the wheel offriction. The lateral movement of the carriage referred to is providedfor in most carriages and is for the purpose of permitting an offset ofthe carriage, that is, a movement permitting the carriage to be moved bymechanical means a slight distance away from the saw so that when thecarriage and log are carried back past the saw, the log will clear thelatter, which movement returns the carriage to a position preparatory toan onset movement, that is, a movement during which the log is beingsawed.

The preferred form of the invention is hereinafter described andillustrated in the accompanying drawings.

In these drawings, Figure 1 is a side elevation illustrating the same;Fig. 2, an end view thereof; Fig. 3, a sect-ion on line a-a of Fig. 1;Fig. 4, a detail section on line 5-?) of Fig. 1, and Fig. 5, a detailperspective view of part of a modified form.

Referring to the drawings, 1 is a side beam of the frame of a saw-millcarriage, 2 is one of the axles journaled at 3, 4 is one of the wheels,and 4: is one of the track rails.

5 is the improved guard and scraper. Removable wheel guard and scrapersections 6 are bolted together at 7 and at their outer ends are beveledat 8 to provide plow points.

Secured to the beam 1 by bolts or spikes 9 are arms 10 which are adaptedto carry the guard along the rail with the carriage upon the operationof the latter. The lower extremity of the arms 10 extends freely intoopenings or pockets 11 between the sections 6, and the openings areenlarged to allow a slight lateral movement of the arms thereintransversely of the track, and the openings also communicate with sideopenings 12 which permit the escape of sawdust. The arms will allow theguard to freely yield vertically when the carriage travels over anuneven portion of the track, owing to the provision of the looseconnection. Such arms 10 extend through closely fitting central openingsin plates 13. These plates rest upon the sections 6 above the openings11 to prevent the entrance of sawdust into the guard. The openings 12are provided so that fine particles of sawdust which may work under theplates 13 will not deposit in or clog up the openings 11. The arms 10also have a very slight longitudinal movement in the openings of theguard in order to prevent binding therewith. The guard surrounds thelower part of the wheel in order to prevent the entrance of saw-dust tothe.- track. The guard does not touch the wheel and by thisconstruction, frictional contact therewith is avoided.

14 are side openings in the sections and adjacent thereto are interiorplow points 15 beveled at an angle to the transverse direction of thetrack so as to throw sawdust from the track rail. Saw-dust or otherrefuse which falls upon the track exterior of the guard will be thrownoff by the beveled ends 8, and should any enter the guard and fall uponthe track, the plow points 15 will throw the same off the track throughthe openings 14. Plate portions 16 cover the track rail beneath theopenings 11 and should saw-dust enter the openings, it would fall uponthese plate portions and be shaken therefrom by the movement of thecarriage, througth the adjacent openings 12. The guard 5 is also adaptedto cover the tread of the rail.

Preparatoryto an offset movement, the carriage is moved by mechanicalmeans in a horizontal plane transversely of the track away from the sawand the arms 10, as they are of less width than the openings 11 movelaterally in said openings 11 while the guard itself remains stationary,and upon the offset movement taking place, the

arms will carry the guard along the rail in a position covering thetread and guarding the wheel. Preparatory to the onset movement, thecarriage in moving in a horizontal plane transversely of the tracktoward the saw, owing to the openings 11 being wider than the arm, willmove the arms 10 in said openings 11 in the same direction, withoutmoving the guard. In Figs. 2 and 3, the position of the arms is shown inthe offset position of the carriage in full lines and in the onsetposition thereof in dotted lines.-

In the modified form shown in Fig. 5, I employ in place of the arms 10of the other form, links 18 which are hinged to plates 19 fastened tothe side beam and which are also hinged to plates 20 fastened to theguard. This hinge construction owing to the provision of theintermediate link 18 hinged at both ends will permit the carriage tomove a suflicient distance in a hori zontal plane transversely of thetrack to permit the carriage to be operated for an offset movement or anonset movement without moving the guard to the carriage. In this form ofthe invention the openings des ignated 11 and 12 in the other figuresare dispensed with.

It is clear that various changes may be made without departing from thespirit and scope of my invention.

Having thus described my invention, what I claim is 1. In combinationwith a saw-mill carriage and wheel adapted for use on a track rail, aguard for the wheel, means carried by the carriage adapted to move theguard. with the carriage along the rail, and means to permit horizontalmovement of the carriage transversely to the rail relative to the guard,the guard being stationary during the horizontal movement, substantiallyas described.

2. In combination with a saw-mill carriage and wheel, a guard for thewheel, and connecting means between the carriage and guard having a freehorizontal transverse play between the carriage and guard, to permit thecarriage to move in a horizontal clirection transversely of the rail,the guard being stationary during the horizontal movement, substantiallyas described.

3. In combination with a saw-mill carriage and wheel adapted for use ona track rail, means to protect the track rail beneath the wheel againstthe falling of sawdust thereon, and means interior of the guard andintegral therewith and having a face at an angle to the transversedirection of the rail adapted to remove saw-dust from the rail,substantially as described.

4:.
